In most a.r.cultur.l a.0}a. in the semi-a.0}d r.gion of the souther. United Sta.es, whea. (Tr.ticum a.stivum L.) pr.duction is a.pr.ma.0} economic a.tivity. This r.gion is dr.ught-pr.ne a.d pr.jected to ha.e a.dr.er.clima.e in the futur.. Pr.dicting the yield loss due to a. a.ticipa.ed dr.ught is cr.cia. for.whea. gr.wer.. a.r.lia.le wa. for.pr.dicting the dr.ught-induced yield loss is to use a.pla.t physiology-ba.ed dr.ught index, such a. a.r.cultur.l r.fer.nce Index for.Dr.ught (a.0}D). Since differ.nt whea. cultiva.0} exhibit va.0}ing levels of sensitivity to wa.er.str.ss, the impa.t of dr.ught could be differ.nt on the cultiva.0} belonging to differ.nt dr.ught sensitivity gr.ups. The objective of this study wa. to develop the cultiva.0}dr.ught sensitivity (CDS) gr.up-specific, a.0}D-ba.ed models for.pr.dicting the dr.ught-induced yield loss of winter.whea. in the Lla.o Esta.a.o r.gion in the souther.

Ca.0}on concentr.tion in HW incr.a.ed with a.decr.a.e in sta.d pr.ductivity (Blu-Lin-Lic).
